KEMET's portfolio of polymer capacitors (KO CAP) is designed specifically for defense applications. The benefits of polymer technology include very low ESR, stable capacitance, high ripple current capability (greater than 3 times that of traditional MnO₂ capacitors), benign failure mode, no piezo electric noise, and improved voltage derating. They are manufactured in the USA. These products are subjected to a rigorous qualification and manufacturing process to assure high quality and reliability for the user community.
